By default Spring Boot did not come with JSP support. Here’s how to set your app to use JSP:

1. Set the project to use tomcat7-maven-plugin rather than spring-boot-maven-plugin
2. Add / ensure following Maven dependencies are setup

   
     org.springframework.boot
     spring-boot-starter-tomcat
     provided
   
   
     org.apache.tomcat
     tomcat-jsp-api
     provided
   
   
     javax.servlet
     jstl
   
   

3. The Web MVC auto configuration feature of Spring Boot sets you up with a ViewResolver with blank suffix and prefix, hence you can place jsp in src/main/webapp/WEB-INF/test.jsp and have your controller return path to it

   
   ("/test")
   public class TestController {
     (method = GET)
     public String test() {
       return "/WEB-INF/test.jsp";
     }
   }
   

Hope this helps!
